start workflow with On EventBridge trigger

[Justin-productOps]

To the best of my knowledge, there is no way to add an event bridge to trigger the workflow developed via a blueprint.
It would be nice if the event bridge resource could be previsioned here but also think that might be asking for too much. I think maybe just the trigger node that enables the workflow to be triggered with a blueprint rather than me needing to swoop it out after the fact.
